Oh well, here goes...

I know a lot of more experienced people out there are gonna be hacked off
with another stupid question, but what's up with this code?

What it's supposed to do is copy a .tim from RAM to VRAM so that it's
displayed on the frame buffer every cycle but for some reason it just
doesn't show up. It's not like I haven't done this before I've had great
success using LoadImage in the past. I've spent pretty much all weekend
looking at other people's code and demos and tuts but none of it has
helped. It's driving me crazy! ARRGGGGHHH!!!

I've tried a putpixel function and that worked fine so I know the buffers
are set up okay.
I've tried my .tim in other programs and it's displayed, then I tried
editing these programs code and PSComUtil kept reporting an error on data
fetch or something?!

Well, enough yammering here's the source from the main function, should be
pretty self explanetory.

Gareth!
I hope it doesn't drive any of you crazy too...

void main(void)
{
	GsIMAGE	green;
	RECT dest;

	init_game ();			// Set up the screen res, d/buffer and joypads
	active_buffer = GsGetActiveBuff();	// Initialise the active_buffer
variable
	
	GsGetTimInfo ((u_long *) (LOGO_ADDR + 4), &green);
	if (green.ph == 256) printf ("TIM Loaded successfully");
	dest.x = 0;
	dest.w = green.pw;	dest.h = green.ph;

	while (! PAD_PRESS (buffer1, PAD_CROSS))	// Exit when X pressed on
controller 1
	{	
		GsSetWorkBase ((PACKET *) gpu_packet_area [active_buffer]);
	
		GsClearOt (0, 0, &ordering_table [active_buffer]);
		
		dest.y = active_buffer * SCREEN_HEIGHT;
		LoadImage (&dest, green.pixel);

		DrawSync (0);
		VSync(0);
		GsSwapDispBuff();
		GsSortClear (0, 0, 0, &ordering_table [active_buffer]);
		GsDrawOt (&ordering_table [active_buffer]);
		
		active_buffer = 1 - active_buffer;	// Flip the active_buffer
	}
	ResetGraph(3);
}
